I still think Porsche have rested a bit on their laurels with this, lots of stuff promised (as always) and not appearing (as always) and now lots of talk of only 10 coming to the UK (as always) to drive sales and pre-orders, which will be show to be utter crap (as always) when another 60 are 'allowed' next year (as always). Most of the improvements here come from the extra 35bhp and the much greater downforce, over twice as much I believe and a much more sorted set up.
